Extending lamp life
The projection lamp is a consumable item. To keep the lamp life as long as possible, you can do the
following settings via the OSD menu.
• Setting Lamp Power as Economic
Using Economic mode reduces system noise and power consumption. If the Economic mode is
selected, the light output will be reduced and result in darker projected pictures.
Setting the projector in Economic mode also extends the lamp life. To set Economic mode, go to the
Picture -- Basic > Lamp Power menu and press / .
• Setting Auto Off
This function allows the projector to turn off automatically if no input source is detected after a set
period of time.
To s e t Auto Off, go to the System Setup > Auto Off menu and press / to select a time period.
The time period can be set from 5 to 30 minutes in 5-minute increments. If the preset time lengths are
not suitable for your presentation, select Disable. The projector will not automatically shut down in a
certain time period.
Timing of replacing the lamp
When the Lamp indicator lights up red or a message appears suggesting it is time to replace the lamp,
please install a new lamp or consult your dealer. An old lamp may cause a malfunction in the projector
and in some instances the lamp may explode. Go to http://lamp.BenQ.com for a replacement lamp.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too hot. Turn
the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator still lights up after
turning the power back on, please contact your dealer. See "Indicators" on page 51 for details.
The following Lamp warning displays will remind you to change the lamp.

Install a new lamp for optimal performance. If the projector is
normally run with Economic selected (see "Getting to know the
lamp hour" on page 47), you may continue to operate the projector
until the next hour lamp warning appears.
Press ENTER to dismiss the message.
